NON-REFILLABLE BOTTLE.

' Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed October 13,1905. Serial No. 282,576.

To all whom it may concern:

Be it known that I, BYRON SHARP, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improve ments in Non-Refillable Bottles, of which the following is a specification.

This invention relates to the type of bottles known as non-refillable bottles.

In the accompanying drawings, forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a sectional view of the neck of a bottle, part of the devices for preventing refilling being shown in side elevation. Fig. 2 is a similar view, (the bottle being tilted downward,) said devices being shown in section. Fig. 3 is a detail showing a pair of grooves formed in the neck of the bottle. Fig. 4 is a sectional view through the valve and connected parts. Fig. 5 is a top plan view of the same, parts being broken away. Fig. 6 is a top plan view of the protecting-cap for the valve, and Fig. 7 is a sectional view of a modification thereof.

The wall of the neck of the bottle 1 contains annular grooves 2 and 3, the former serving to retain in position the valve, preventing the refilling of the bottle. The groove 3 lies between the annular flange 4 and the neck-wall and is intended for the reception of a suitable packing 5, illustrated in the drawings as consisting of a rubber annulus. Same may be made, however, of aluminium or other suitable material. I prefer to utilize a resilient material, for reasons which will hereinafter appear.

The valve 6 is hinged at 7to a ring 8, formed of aluminium or other suitable noncorrosive material, to which are fastened, by screws 9 or other suitable means, a pair of leaf-springs 10, the unattached portions of' said springs projecting in opposite directions relative to .each other. A coiled sprin 11, cooperating with the hinge 7, normally c oses valve 6, being of sufficient strength for that purpose, yet being also sufliciently yielding to allow valve 6 to open under the pressure of the liquid in the bottle when same is tilted to the position shown in Fig. 2. The lower side of the valve 6 is provided with an annular flan e 12, which fits into an annular groove 13, orrned in the upper surface of the ring 8, the whole of the valve 6 fitting into a countersink 14 in the upper surface of the ring 8, so as to lie flush therewith, and thus present no projection toward the exterior of the bottle. A peripheral groove 15 in the ring 8 receives the leaf-springs 10 at their point of attachment to said ring and is adapted to re ceive even the protruding portions of said springs when the ring 8 and connected parts are first introduced into'the narrow part of the neck of the bottle. The opening in the neck of the bottle is narrowest at its mouth, but gradually increases in diameter until it. reaches its maximum at a point 16 approximately adjacent the lower end of the cork 17, at which point an angle is formed in the interior of the neck of the bottle, the diameter of the opening therethrough gradually decreasing from that point downward until it is narrowest immediately above the groove 2. While passing through said narrow portion, as well as when passing throu h the mouth of the neck of the bottle, the sprmgs 10 will seat in the groove 15.

Fixed to the ring 8 and superimposed thereabove is a hemispherical cap comprising a stationary member 18 and a movable member 19, pivoted at 20 to the fixed member 18.

The pivoted member 19 is either made heavy upside down or tilted into the position shown in Fig. 2. In Fig. 7 is illustrated a modification in which a shoulder or ridge formed in r the member 18 is substituted for the pin 22. (Shown in Fig. 1.) It will also be observed that the weighted shoulder 21 can be utilized as a stop by so arranging it as to strike the nearest edge 23 of the member 18. When the bottle is returned to its normal position, the member 19 falls from the position shown in Fig. 2 to that illustrated in Fig. 1.

. The cap formed of the members 18 and 19 constitutes a protection for the valve 6 to prevent its being held open from the oustide of the bottle; but the valve itself contsitutes the means for preventing reentrance into the bottle of any liquid. As an additional precaution, and so as to prevent the insertion of a wire, for instance, to hold up the member 19 and to catch the valve 6 open while the bottle is in the position shown in Fig. 2, a guard-disk 24 is provided in the neck of the bottle at a point above the member 18. Said guarddisk 24 may either be formed of reticulated material or, as shown in the drawings, it

may take the form of a pair of diaphragms water-tight.

' of the ring 8 upon the packing 5 from the top renders said connection water-tight and also the openings 25 in the upper diaphragm being arranged in staggered relation to those in the lower diaphragm. The disk 24 is pro vided with the pair of springs 26, attached to it and operating like the springs 10, hereinabove described, and fitting into the groove 27, the springs 26 and groove 27 being preferably narrower vertically than the vertical width of springs 10 and groove 2.

The operation of the device is as followsz 'The bottle having been filled, annulus 5 is slipped down the neck of the bottle and into ,place in the groove 3, or it may be attached to the ring 8 and carried to its said position,

when the ring 8 and connected parts are introduced into the neck of the bottle. When the packing 5 consists of resilient material, it is made slightly higher than groove 3, and when the ring 8 is pressed down thereupon said packing 5 'is expanded laterally, so as more completely to fill the groove in which it is placed, and thus to render the device more Moreover, the close pressure I it has been pushed into place and the springs 10 have sprung into the groove 2, and the bite of the springs 1O on the upper wall of the groove 2 and the upward pressure of the packing 5 render the device stationary. When it is desired to pour out some of the contained liquid from the bottle, it is tilted into the position shown in Fig. 2, whereupon the pivoted member 19 swings out of the way of its own weight, and the liquid causes the valve 6 to open against the mild pressure of spring 11. As soon as the bottle is returned to its normal vertical position the pressure of the liquid against the valve 6 is the valve, while the member 19 returns to the relieved, and the spring 11 positively closes position shown in Fig. 1 by gravity.

Havingthus described my said invention, what I claim, and desire to secure by Letters Patent, is-
